(57) [Summary] [Purpose] Effectively perform a rapid cooling operation that rapidly lowers the temperature of the freezer. [Composition] An electric refrigerator has a function of a rapid cooling operation capable of rapidly reducing the temperature of a freezer by continuously operating a compressor for a predetermined time, and defrosting when the accumulated operation time of the compressor reaches a predetermined time. There is a function to start driving automatically. In a conventional electric refrigerator, if a predetermined switch is operated, the rapid cooling operation can be started at any time unless the defrosting operation is in progress.For example, even when the defrosting operation is about to start soon, the rapid cooling operation is started. I was able to do it. However, when the defrosting operation is about to start, a large amount of frost is attached to the evaporator, so that the temperature of the freezer compartment cannot be rapidly reduced even if the quenching operation is performed. Therefore, as shown in FIG. 2, when the defrosting operation is started within a preset rapid cooling operation time, the defrosting operation is prioritized, and the rapid cooling operation is started after the defrosting operation is completed.

Description of the Related Art In an electric refrigerator, a function of automatically starting a defrosting operation when a cumulative operating time of a compressor reaches a predetermined time, and a compressor operating continuously for a predetermined time to rapidly increase the temperature of a freezing room. Some have the function of quenching operation that can be reduced to. The function of this rapid cooling operation is used when shortening the ice making time or quick freezing food. The time required for the defrosting operation varies depending on the amount of frost attached to the evaporator, etc., but the time required for the rapid cooling operation is constant because it is preset in the storage unit of the control unit. The defrosting operation is automatically started when the accumulated operating time of the compressor reaches a predetermined time, but the rapid cooling operation can be started by a predetermined switch operation, and the defrosting operation must be started first. For example, it is started even immediately before the start time of the defrosting operation.

発明においては、このような不具合が生ずることのない
電気冷蔵庫を提供することを目的としている。However, as described above, the function of automatically starting the defrosting operation when the cumulative operating time of the compressor reaches a predetermined time, and the time when the defrosting operation is not started, However, in an electric refrigerator equipped with a function that can start the rapid cooling operation, the rapid cooling operation can be performed at any time by performing a predetermined switch operation even if the defrosting operation start time is within the preset rapid cooling operation time. Will be started. Thus, when the defrosting operation start time is within the rapid cooling operation time, a large amount of frost has already adhered to the surface of the evaporator. When the rapid cooling operation is started at such a time, a larger amount of frost adheres to the evaporator, and the cooling capacity is significantly reduced, so that the effect of the rapid cooling operation is diminished. Further, if a large amount of frost adheres to the evaporator, the time required for the defrosting operation also becomes longer, which causes a problem such as a decrease in cooling efficiency. Therefore, it is an object of the present invention to provide an electric refrigerator that does not cause such a problem.

後に急冷運転を開始させるようにしている。Needless to say, the microcomputer constituting the control section 4 is provided with a timer circuit section, a storage section, a comparison circuit section, etc., and defrosts when the accumulated operating time of the compressor 7 reaches a predetermined time. The operation of the compressor 7 is stopped for the operation, and the energization of the defrost heater 8 is started.
Further, since the blower 6 and the compressor 7 are continuously operated for a predetermined time by operating the quenching switch 1, it is possible to shorten the ice making time and quick freeze the food, but in this embodiment, it is set in advance. When the defrosting operation start time is within the rapid cooling operation time, the defrosting operation is prioritized and the rapid cooling operation is started after the defrosting operation is completed.

The remaining time until the defrosting operation is started is calculated from the difference between the operating time and the actual integrated operation time. In the next step ST3, the remaining time until the defrosting operation started calculated in step ST2 (starting time of the defrosting operation) is compared with a preset rapid cooling operation time, and the defrosting operation time is removed. A determination is made as to whether there is a start time for frost operation. When the start time of the defrosting operation is not within the rapid cooling operation time, that is, when the cumulative operation time of the compressor 7 which is the start time of the defrosting operation before the end of the rapid cooling operation does not reach the predetermined value Proceeding to step ST4, the rapid cooling operation is started.

られ、通常運転に戻される。In the next step ST5, the quenching operation time is counted, and it is judged whether or not the preset quenching operation time has been reached, that is, whether the quenching operation has ended. When the quenching operation ends, step ST6 follows. Then, the defrosting operation is started. If it is determined in step ST3 that the start time of the defrosting operation is within the rapid cooling operation time, that is, even if the rapid cooling operation is started, the accumulated operation time of the compressor 7 is not yet terminated before the rapid cooling operation ends. If the predetermined value is reached and the defrosting operation is started, step ST
7, the defrosting operation is immediately started prior to the quenching operation. In the next step ST8, it is determined whether or not the defrosting operation has ended. When the defrosting operation ends, the process proceeds to step ST9, and the rapid cooling operation starts. In step ST10, it is determined whether or not the rapid cooling operation has been performed for a predetermined time, and when the rapid cooling operation is completed, the process proceeds to step ST11 to return to the normal operation.

間が短縮されるので消費電力の節約にもなる。As described above, in the electric refrigerator controlled as described above, when the defrosting operation is started within the preset quenching operation time during the quenching operation, the defrosting operation is prioritized. Since the quenching operation can be started after the defrosting operation is completed, there is no frost on the evaporator during the quenching operation, the cooling efficiency is improved, and the defrosting time is shortened, which saves power consumption.
